    We're making great strides in generating electricity - but is much being done to increase our ability to store it? Presumably that would go hand-in-hand with the on/off nature of generating from Mother Nature?

    You could make 18 trips in the Delorian with all that power!

    It is obvious that in the future renewable energy sources are going to become more prominent in our everyday lives but as people are suggesting there are certain people hindering the progress of developing our renewable energy sources. An example of that is here.

    A classic example local to me is a wind farm that was turned down so they built a gas fired power station instead!

    The councillor was concerned about the amount of noise the turbines would produce! :coffee:

    Actually I think the wind turbines were planned after they built the gas power station, the problem was that the people overlooking the gas power station said they were an eyesore and would lower the value of the houses. Like the gas powered station does not, then again if there were wind turbines there and they wanted to pull them down then the same people would have probably complained. Sometimes you need to not listen to the public.

    I was involved in a field experiment with solar panels, both hot water and PV, while on a course at CAT.
    What we found was that during two months of non stop rain in June and July one year the solar hot water produced plenty of hot water and some good results for the experiment.
    The PV, on the other hand, produced a flat line graph of zero output except for one blip where the sun came out for two hours. During that two hour blip there was a big dip where one of the observers observed a bird flying low over the panel casting a shadow.

    Current PV just isn't that effective unless there is proper sunshine. It just never paid to install it until the feed in tariff made it viable.

    Solar water heating, on the other hand, works and should be much more common then it is, but there is no feed in tariff for it I think. Could be wrong about that.

    I was impressed when in Germany how much PV they have there.

    I noticed that too when I was last over there. See what happens when the people tell the government they don't want any more nuclear power plants :p:

    The Solar Roadways project is working to pave roads with solar panels that you can drive on!!

    Co-founder Scott Brusaw has made some major steps forward- watch the video and then check out the website for more: http://www.solarroadways.com

    Good idea or not practical to have roads made out of glass?

    It's a fascinating idea and watching the video it appears they have thought about it well.

    If they can make the panels durable and grippy enough to work in practice I think this could be a good project. Apart from the power generation, I like the idea of the electrical and 'phone services being integrated into the panels - that would remove a lot of unsightly and vulnerable overhead lines.

    Maintenance could also be easier if the panels are made easy to lift and refit.

    There is potential here.:thumbsup:

    I can see it working on those long dessert roads that are hardly used. Can't see it working here though with roads full of cars and little sun.

    I think cost and the lack of sun are the two main problems. Also, the fact that it can only heat up water at the moment means that it will take a while to recoup the investment. In Spain, solar power is more efficient and cheaper to install, because there's been a lot of investment into research and development, and they're actually advising America on expanding their use of solar power. Despite the recession, solar power companies are still turning in profits.

    "The world’s largest solar power field has been switched on in India’s western state of Gujarat. Accounting for 214 megawatts of photovoltaic solar capacity, it becomes larger than China’s 200 MW Golmud Solar Park, which previously held the record."

    It would be good if countries get into a "mines bigger than yours" solar race like we saw with things like super computers.

    I don't think the UK will ever be right for this kind of thing. Land prices are too high and not enough sun. I still think our coasts are a much better resource here.
